Is it a lie to call carbon dioxide a health hazard?

We breath it everyday, but when we also get enough oxigen, we're healthy.

Carbon dioxide is an "environmental hazard."

It's a STRETCH to say "health hazard." Why do they have to do this?

Why can't EPA address environmental hazards? Why do these environmental hazards have to be defined as health hazards before EPA can act?

I don't know, I'm no lawyer.

Or, here's an idea. Here's the STRETCH.

Cars spew out lots of carbon dioxide and they also kill tens of thousands of Americans each year in auto accidents as well as obesity.

Cars are a health hazard.

Is that the STRETCH they are using?

Probably not, but here's an interesting thought. "There's "cause and effect," and there's also "correlation."

It works.

Is this what they are thinking? I'm no lawyer.
